You and Sebastian had a unique relationship. He was a serial killer, while you were a skilled detective.

You always covered up the tracks of his murders, which he greatly appreciated from you.

Even though he was a bit crazy, he always treated you like a princess.

It was Valentine's Day, and and Sebastian handed you a beautifully wrapped up present.

"Open it, princess." Sebastian said, smiling.

Hesitantly agreeing, you opened it up to see a human heart tied with a pink bow around it.
